From 1988 to 2006, between 40% and 60% of all first-time community college students are referred to and enroll in at least one developmental education course; some colleges reported as high as 80 percent (e.g. Attewell, Lavin, Domina, & Levey,...

Pulmonary complications associated with persistent respiratory muscle weakness and paralyses are critical problems faced by patients with chronic spinal cord injury (SCI). The aim of this dissertation is to investigate the role of neurological...

Nontraditional college students--Kentucky--Louisville; English language--Rhetoric--Study and teaching (Higher); College freshmen--Kentucky--Louisville

This dissertation explores the role first-year composition (FYC) courses play in the academic lives of working-class adult students in the University of Louisville, an institution that, during portions of its long history, has been a valuable...

Data centers (DC) are the core of the national cyber infrastructure. With the incredible growth of critical data volumes in financial institutions, government organizations, and global companies, data centers are becoming larger and more...

This dissertation focuses on the mechanisms and implications of perceptual learning of binocular interactions. Perceptual learning is an important means of adapting to the changing environment, demonstrating the possibility of neural plasticity in...

Overweight and obesity is a major contributing factor in an estimated 70% of all obstructive sleep apnea (OSA) cases. Approximately five percent of the adult population has OSA, and the numbers continue to soar with the rising prevalence of...

In this work, micro fabrication techniques are explored not only to simplify the production of complex lab on-a-chip devices (LOC), but also micro fabrication will be utilized to create intelligent design features that will enhance an...

The research in this dissertation describes a simple electrochemical approach for fabricating nanoscale (metal/metal) or molecular (metal/polymer or self assembled monolayer (SAM)/metal) junctions. The fabrication involves metal deposition on one...

Although there is a vast body of literature to support multiple positive outcomes related to positive student-teacher relationships, no prior study has investigated student-teacher relationships within the context of a residential treatment center...

Multistate models are a type of multi-variate survival data which provide a framework for describing a complex system where individuals transition through a series of distinct states. This research focuses on nonparametric inference for general...

This study addressed the job satisfaction of new teachers in Jefferson County Public Schools (JCPS). in Jefferson County, Kentucky. The JCPS district is the 29th largest in the United Sates and serves over 98,000 students. Understanding what...
